The UTM letters are an optional feature; QGIS only requires to know if you are North (37N) or South (37S) of the aequator. So 37N should be good for you. You have to make sure that coordinates you add manually have not stripped off the first digits.

The perimeter would probably be between .7 and 1 mile or the equivalent in metric. The value given in the column is 0.0133. How do I tell what the unit is supposed to be for these calculations? (And how would I set/change it?) I've looked in SettingsOptions on the main QGIS window and the layer and haven't found anything. I did find where one sets the units for the measure tool and that is set to meters, but I am assuming the units selected for the measure tool aren't necessarily the same as for the calculation for the geometry. The perimeter is calculated in units of the layer. If that has degrees (like EPSG:4326), the perimeter result is surely nonsense. You have to reproject your datasource to a projected CRS that uses metres, feet or miles to get a useful result. Note that the measurement tool behaves different in this point.

Then I went into QGIS and attempted to open it as a vector layer, selecting files of type:Keyhole Markup Language. The title appears under layers, but it doesn't actually display. I thought it might be a projection problem, so I tried zoom to to layer but that doesn't seem to have any effect. Any help would be much appreciated. I could georeference the file myself, but since it has already been done, I was trying to avoid duplicating that work. The KML driver is designed for importing vector data (points, lines and polygons). From your description, the .kml seems to display a raster file, therefore nothing gets imported. The same might happen if the kml only contains an internet link to the raster file. You can however look into the kml file with any text editor, and look out for georeferencing information. That can be used to build a .vrt file, which serves for QGIS as a wrapper the same way as your kml does for Google Earth. Mabe you can provide the dwomload link of the original kmz to help further.

In short the osm data attached appears to be loaded correctly into the spatialite database, but extraction from the database into qgis is incomplete. No, not really. You can load the data alternatively with Add vector layer, which gives me 35 lines and 40 polygons, instead of 6 and 15 with the Vector-OSM import. Looking into the spatialite database with spatialite GUI, I still see only 6 lines and 15 polygons, so they are not improted into the database. 1.

Google/Web Mercator datasources may shft to about 20km vertically if the transformation method is wrongly implemented (like EPSG:3395).

I have a map that I want to keep in the BC Albers (meters) projection but I also want to have the coordinate display show in decimal degrees. It seems with QGIS I currently cannot have it both ways. Yes, you can: http://code.activestate.com/recipes/578692-qgis-startup-script-change-display-of-coordinates/ Rename it to startup.py and save it to C:/users/username/.qgis2/python (not .qgis as mentioned in the text). I got that working, but you will get nasty errors if you leave QGIS while the CRS is set to some local system. Deleting the \HKEY_CURRENT_USER\Software\QGIS\QGIS2\CoordsConf entry in the registry solved the problem. I'm not sure how to clear that for other OS.

You have to save your layer using rightclick, Save As... to another name and EPSG:32733, and add the result to the canvas. From that, you can export the vertex coordinates to CSV with the mmqgis plugin. For a polygon, you will not get the coordinates into the attribute table, because the whole polygon has only one row in the attribute table.

Am 11.03.2015 um 10:55 schrieb Nicole Stoffels: I have an old ArcGIS project, that was build before we switched to QGIS. I have already worked on it with my older QGIS versions (= 2.6) and added new shape files to an ArcGIS georeferenced map. Now I opened it with my new QGIS version 2.8. My shape layers are displayed correctly but my old ArcGIS maps are not shown underneath the shape layers. I can zoom to them, but they suddenly have a completely different projection (a strange user CRS), while the original EPSG of the project is 31466 (Gauss-Krueger Zone2). Guass-Krueger usually has a datum shift, but ARCGIS datasources don't store that inside the raster or vector files. QGIS behaves different, and stores datum shift or EPSG code in .qpj files only for vector files. That might be the reason why you get the offset. It might help to change the CRS of the layer from the user-defined to the official EPSG code. The datum shift from Gauss-Krueger to WGS84 is not constant, but varies across Germany. The official EPSG code has an average value for Germany. Better values can be found here: http://lists.osgeo.org/pipermail/qgis-user/2012-August/019083.html and in the links given there.

When do this for the span of lower Manhattan in New York City, I get a beautiful set of map data that is unfortunately missing quite a few major streets. Exporting as polygons doesn't omit those streets from the map but I need the center lines. Importing the .osm file directly gives the same results of missing streets. I've tried 4 times with same results. What am I doing wrong I can replicate your error. Maybe the data is just too big and crashes the importer. Unfortunately, you get no error message. However, you can still use the downloaded .osm file which is complete. As Anita suggests, you can use ogr2ogr -f SQLite -dsco SPATIALITE=YES newyork.db ny.osm or just drag and drop the .osm file into the legend, and select the lines for importing. This needs quite some time, and you should save the result to a shapefile for further use. Both methods use the GDAL osm driver, hence contain the same amount of data (both 53607 lines from my canvas extent instead of 37602 from the importer). Using osm2pgsql, I get 59667 lines. Some incomplete multipolygon relation members are treated differently in GDAL and osm2pgsql.

The Real Question: Why does my browser not find qgis_mapserver.fgci.exe? I strongly recommend to stick to one architecture. Since OSGEO4W 64-bit does not include apache (see http://download.osgeo.org/osgeo4w/versions_diff-x86-x86_64.html) , I suggest to run everything on 32-bit, as included in the OSGEO4W packages. A mixture of 64-bit and 32-bit software will most likely run into problems at one point.

Re: [Qgis-user] VIIRS geolocation data
Hi Mitch, you should better include the whole list in your reply, so that others can benefit (or help). If you want to run gdal commands in a QGIS installation, you have to run the OSGE4W shell, then enter commands inside the shell. This looks quite old-fashioned, and you need to remember old DOS-commands to navigate between folders, but otherwise the environment for GDAL is not setup correctly. Am 11.05.2015 um 21:56 schrieb Dr. Mitchell Andrew Schull: Andre, My gdal doesn’t recognize VIIRS datasets now! Its odd because gdal works perfectly in qGIS. Any idea why all the gdal capability is not available in qGIS? I could just do it in the customized gdal scripts in gdal_transform but it doesn’t allow me.

I think you have georeferenced it. http://www.digital-geography.com/qgis-tutorial-i-how-to-georeference-a-map/#.VU1W52a23FQ It is not that easy. The data is raw data from a satellite flight. The HDF contains several subdatasets, including longitude and latitudes of every cell. Unfortunately, the cell coordinates are not equally spaced, and there is no CRS given. The best result I get is transforming the longitude, latitude and aerosol subdatasets with gdal_transform to XYZ format, then stitch them together with LibreOffice Calc, and import them as delimited text. It is possible to extract single bands with gdalwarp. This seems to work, but the GCP information inside the file is wrong. Longitudes are added by 180°, and the last line of GCP matches 0/0 to 0/0, which makes no sense to me. Reading the data with python code inside a plugin might be an alternative.
